SAND-DISTRIBUTING MACHINE. I l i 4rPatented Aug'.` 1, 1905.

Application filed January 14, 1906. Serial Noi-241,031.

Be it known that I, GIUSEPPE GIoIoSA, a

citizen of the United States, residing at East Boston, in the county ofSuffolk and State of Massachusetts, have invented new and useful'Improvements in Sand Distributing Machines, of which the following is aspecifica- 'tion.

This invention relates to an improvedmechanism for distributing sandupon railroadtracks in advance of the wheels of the car to' prevent saidwheels from slipping upon the rails.

Said invention is an improvement upon the device for feeding sand torailroad-tracks invented by me, for which Letters Patent of the. UnitedStates were issued to me December 6, 1904, No. 776,782, and the generalconstruction and operation of the device of this 'invention issubstantially the same as the invention of said Letters Patent No.776,782.

The object of this invention is to provide means for thoroughly dryingthe sand and keeping it heated, so' that it'will not freeze 'and sothat. it will iow freely downwardly froml the chute from thesand-receptacle and 'be delivered in front of the wheels of the car uponthe track.

The invention consists in the combination andarrangement of parts setforth in the following specication, and particularly pointed out in theclaims thereof. l

Referring to the drawings, Figure 1 is a side elevation of a portion. ofa car with my improved sand-distributing mechanism at- -tached thereto.Fig. 2 is a central longitudinal section, partly in elevation, of thesame. Fig. 3 is a transverse section, partly in elelvation, taken online 3 3 of Fig. 2. 'Fig 4 is a detail section taken on line 4 4 of Fig.2. Like numerals refer to like parts throughout the several views of thedrawings.

In the drawings, 5 is a portion of a car of -any desirable construction,6 the truck, and

7 the ioor of the car.

Y 8 is a receptacle for the sand, made, prefer.- -ably, of sheet metal,being cylindrical in form and fastened by brackets 9 9 to a base 10. Inthe interior of the receptacle 8 is a partition 11, consisting of aninverted cone provided with an aperture 12 at the bottom thereof. Saidpartition divides the interior of said sandreceptacle 8 into twochambers-an upper chamber 13 and a lower chamber 14. The

'sand-receptacle 8 opens at its lower end through an'aperture 12 into anaperture 15,

formed in the bottom plate 16. The sides of the aperture 15 are lclosedby flanges 17 17, projecting upwardly from the base 10, and beneath theaperture 15 is located a slide 18, having a hole extending therethrough,and beneath the slide 18 is attached a chute 20, which is connected byla coupling 21 to the under side of the base 10, the interior of saidchute being in alinement with the hole 22, formed insaid base 10.

The Slide 18 is guided in ways 23, formed in the base 10, and is movedtoward the right,

Fig. 2, by springs 24 and toward the left by a segmental gear 25, whichmeshes into a rack 26, formed uponsaid slide, and is pivoted at 27 to abracket 28, fast to the base '10. The

segmental gear 25 is provided with a projecting arm 29, integraltherewith,said gear and arm forming together a segmental gear-lever, thearm 29 being connected by a link 30 to a treadle 31, pivoted at 32 to abracket 33, fast to the under side of the platform 7. The treadle 31 ispushed downwardly by a pin 34, which is depressed by the motorrnanwhenever it is desired to distribute -sand upon the .left open tocommunicate with the interior of the upper chamber 13. In the lowerchamber 14 is located a device for imparting heat to the sand,consisting, preferably, of a coil of wire 38, heated by an'electriccurrent.- Said lower chamber is provided also with apertures 39 and isconnected by'a passage 40,

formed in the slide 18, to the interior of the agitator 35.

The partitionll is formed, preferably, `of corrugated sheet metal, saidcorrugations being illustrated in detail in Fig. 4 of the drawings, theobject of these-corrugations being to allow the dry heated sand at thebottom of the` mass of sand in the receptacle to follow the spacesbetween said crrugations and be guided by them downwardly through `theapertures 37 to the interior of the agitator 35.

The depressions formed by the corrugations upon the under side of thepartition 11 are preferably filled with portions of the heatingcoil 38,so that said corrugations are at all times thoroughly heated, and thesand coming into contact with the convex upper side of said corrugationsis kept dry and free from moisture, so that it will readily feed, guidedby said corrugations, downwardly in the spaces between said corrugationsupon the upper side of the partition 11 through the apertures 37 to theinterior of the agitator 35, and thence falling downwardly will passthrough the apertures at the bottom of the partition 11, through theaperture in the slide 18, and thence downwardly through the chute 20, tobe finally delivered upon the rails in front of the car-wheels.

The general operation of the device hereinbefore described is asfollows: Assuming the receptacle 8 to be filled with 'sand to a pointabove the conical partition 11 and the parts to be in the positionindicated in Fig. 2, if the motorman desires to distribute sand upon therail he presses his foot upon the pin 34, depressing the treadle 31 atthe left-hand end thereof and raising the same at the right-hand endthereof. At the same time through the link 3() the segmental gear-leverand segmental gear 25, together with the arm 29, are rocked upon thepivot 27, moving the slide 18 toward the left from the positionindicated in Fig. 2. Upon releasing the pin 34 the springs 24 will drawthe slide 18 toward the right to the position shown in Fig. 2. Duringthis reciprocatory motion imparted to the slide 18 the heated air in thelower chamber 14 is forced through the passage 40 to the interior of theagitator 35 by the air which rushes in through the apertures 39 byreason of the motion of thecar. Said air thus rushing through theapertures 39 forces the air in the lower chamber 14 through the passage40 and outwardly through the top of the agitator and through theapertures in said agitator, thus drying and warming the sand as theagitator passes therethrough.

It will be understood that the heating-coil 318, located in theconcavities formed in the under side of the partition by thecorrugations 41, also dries and thoroughly heats the sand adjacent tothe corrugated partition 11, and as said sand is dried adjacent to saidpartition it passes downwardly into the spaces between the corrugations41 upon the upper side of the partition 11 into the interior of theagitator and downwardly through the chute 20, as hereinbefore described.It is very essential in a device of this character that thevsand shouldbe thoroughly heated, dried, and agitated in order that the same mayflow down the chute to the track upon a single motion of the pin 34,hereinbefore described.

WhileIhave describedaheated electric coil as being preferably used foraheating` device in this connection, it is evident that a steamcoil orhot-water coil may be used if more convenient or desirable.

Having thus described my invention, what I claim, and desire by LettersPatent to secure, is-
